1988 Mazda RX7 Two Wheel Drive Manual 100000 miles

When I accelerate my car won't idle also when it reaches 4000rpm it sputters and won't accelerate unless I feather the throttle

Lack of acceleration,chugging,hesitating,bogging etc. could be caused by one of the following below.

Inspect and test all the following listed below and get back with some results

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard.
